Simple, general, realistic, robust, analytic tokamak equilibria. Part 2. Pedestals and flow
Abstract
Part 1 described a wide range of analytic tokamak equilibria modelling smooth limiter surfaces, double- and single-null divertor surfaces, arbitrary aspect ratio, elongation, triangularity and beta. Part 2 generalizes the analysis to further include edge pedestals and toroidal flow. Specifically, edge pedestals are allowed in the pressure, pressure gradient and toroidal current density. Also, an edge-localized contribution to the bootstrap current is treated. In terms of flow, analytic solutions are obtained for two cases: a $γ = 2$ adiabatic and a $γ = \infty $ incompressible energy conservation relation.
